Question

the triangles △pts and △qtr are congruent. identify their common side or angle
the common part is tq
to
∠t
pt
rt
∠p
∠q
ts
∠pst

Explanation:

When two triangles are congruent, we look for parts that are shared. In \(\triangle PTS\) and \(\triangle QTR\), the angle \(\angle T\) is common to both triangles. It is the vertex - angle that is part of both \(\triangle PTS\) and \(\triangle QTR\).

Answer:

\(\angle T\)
